Chemical reaction between alkali components and alkaline reactive minerals in aggregate, producing of a hygroscopic gel and swelling of the gel were simply modeled. Moreover, transportation of both alkali ions and moisture content in concrete was also evaluated by considering the nonstationary diffusion equations in the analysis. Parametric analyses with single aggregate model were conducted in order to confirm the applicability of the proposed model. As the results, it was shown that the proposed model was useful to evaluate ASR expansive behavior, since effects of alkali content and humidity on ASR were simulated qualitatively., 平成26年度関西大学若手研究者育成経費 研究課題「準微視的メカニズムに基づいたコンクリートのASRシミュレーション」}, pages = {101--106}, publisher = {公益社団法人プレストレストコンクリート工学会}, title = {ASRの化学的・力学的現象を考慮したメゾスケール解析手法の構築}, year = {2014} }
